*** COMMANDS to MANIPULATE GPIO ***
The GPIO command interface uses combination of 2bytes, a mask, and value, packed
into a hex word for each command. The first byte, the mask, determines which GPIO
are to be affected, and the second byte is the value to set.
15 --------- 8 7 -------- 0
<hexword> = MASK[7...0] VALUE[7..0]
There are 2 registers used to control the GPIO, the first is a direction register. This
controls whether the GPIO is an input or an output. The second register is the value to
apply to the GPIO if set to an output, or is the value of the built-in weak pull-
up resistor if
the GPIO is set to an input. These settings are immediate, and do not survive a power
cycle.
Examples: S@,8080 sets GPIO-7 to an output
S&,8080 drives GPIO-7 high
S&,8000 drives GPIO-7 low
Power-up values: These 2 registers will apply the direction and values upon each
subsequent power-up:
Examples: S%,0101 sets GPIO-0 to an output on power-up
S^,0303 drives GPIO-0 high, and pulls up GPIO-1.
Multiple bits can be set, any bits with a mask of 0 are left unaffected for the command.
Some GPIO are checked at power-up time to perform certain functions, so care must be
taken when manipulating them. GPIO3, 6, are used to automatically set master mode,
and auto discovery. If it is desired to use these GPIO for other purposes at power-up, a
special command must be used to disable their being sensed at power-up time. This
command is “SQ,4<cr>” this will set a flag in a stored register that is read at power-up.
